Glazing in building facade plays a very very important role. The requirement of glazing is to enter the light and fresh air and also offer view to connect interior living space to the outdoor. However, glazing and windows are major source of unwanted heat gain in buildings especially during summers Read more…
Solar PV technology is rapidly advancing every year and applications are identified for specific use. One of the latest development is the introduction of flexible solar cells and modules. Traditionally, solar cells are flat and non-flexible type if they are made of crystalline silicon. Hence, it is difficult to adopt Read more…
Net Metering allows solar consumers to supply access power back to the grid and reduce their electricity bill. It is a crucial policy decision by any state providing net metering facility. Without it, the widespread penetration of solar rooftop is not possible as of day. In some of the states Read more…
Climate Zone Map of India Climate Zones The first step in following the ECBC is determining the appropriate climate zone of the building site which willdictate the specific requirements for design and construction of the buildingsystems and components. India possesses a large variety of climates, which canbe broadly categorized into Read more…
The SHGC and U-factor ratings are the most important items to verify during inspections. Building professionals should verify that the ratings of the installed windows, doors, and skylights meet or exceed the ratings specified on the plans. It is also important to verify that the same window area has been Read more…
The sun emits visible solar radiation in the form of light and infrared radiation that cannot be seen, but causes heat. Spectrally selective glass transmits a high proportion of the visible solar radiation, but screens out radiant heat from the sun – significantly reducing the need to cool a building’s Read more…
Low-e stands for low-emissivity and refers to a special coating that reduces the heat transfer of a window assembly. Low-e coated products that reduce solar heat gain can be produced by adding a metallic coating either while the glass is in a molten state or by applying to the glass Read more…
Prescriptive Requirements for Fenestration Location : Gurugram Climate Zone : Composite (Lat: 28° 42’ N; Long: 77° 54’ E) Building Type : Daytime Use Building Roof Area : 409 m2 Roof Insulation : Rigid Board 25 mm with R = 2.1 m2·K/W Wall Area : 930 m2 Wall Insulation : Read more…
Solar PV market is predominantly using Mono crystalline and Poly crystalline solar panels. As the name suggest, Mono crystalline cells are made from a single continuous crystal structure. Mono crystalline panels can be identified visually as the cells appear as a single flat colour, generally dark black. The solar cell Read more…
In recent years we have seen that many commercial buildings are coming up as a whole glass buildings. In Indian context buildings with full glass is not desirable as the larger amount of glazing leads to a huge amount of heat gain of overall building. Hence, it becomes important to Read more…
